I noticed that AIGLX consume lots of CPU (about 30% when I move a window, sometimes to 100% when I rotate the cube very fast) . It is said that AIGLX is designed not to consume as much CPU power. What causes that much CPU consumption? Do you have any plans to optimize AIGLX support? I have Xelo FX5200, Fedora Core 6, 1.0.9629 drivers (Livna's package; the same result with nVidia generic tarball package). I tried AIGLX with some integrated Intel graphic card and it works perfectly, it consume almost none of CPU power.
